His new ad is in response to several that Esty has aired in recent weeks claiming that Greenberg wants to dismantle Social Security. It cites a Hartford Courant “fact check” that described one of those Esty ads as false and misleading.

But Greenberg maintains the humorous tone that he established in his first ad of the campaign cycle, which featured a group of barking dogs at an animal shelter charity he founded in Bloomfield.

In his new ad, a dog is shown barking at a TV playing Esty’s attack ad. It then cuts to Greenberg standing next to his father, Jerry. Greenberg assures voters that no one would lose Social Security benefits under his plan, and his father chimes in with a tongue in cheek, “They’re barking up the wrong tree.”
